Human-triggered avalanches are likely as the new snow settles.
Areas unaffected by wind will offer the best riding quality and the lowest avalanche hazard.
70 to 120 cm of recent snow has fallen with strong to extreme winds. Watch for reactive wind slabs at treeline and alpine elevations.
A crust with surface hoar or facets overtop is buried at least 100 cm deep and may persist as a problem at treeline and alpine elevations. Storm slabs could step down to this layer, creating larger-than-expected avalanches.
Wind slab avalanches up to size 2.5 were reported on all aspects at treeline and above throughout the region on Saturday.
Approximately 80 to 120 cm of storm snow has accumulated since early this week, with strong southerly winds redistributing snow throughout the storm.
At treeline and above, recent storm snow overlies either a crust of variable thickness or firm, settled snow. Below treeline, new snow sits on a thin crust, with moist or isothermal snow beneath.
A January 26 crust, with possible surface hoar or faceted snow above or below it, is now buried over 100 cm deep and is likely limited to higher elevations. At lower elevations, it has likely been rain-soaked and destroyed.
The remainder of the mid and lower snowpack is generally well settled with no significant concerns.
